Sunspot update: in October solar activity increased after September’s crash
Time for this month’s sunspot update. As I have done every month since I started this website in 2010, I am posting NOAA’s most recent update of its monthly graph tracking the number of sunspots on the Sun’s Earth-facing hemisphere, adding some additional details to provide context.
In October, following a crash in activity in September, the Sun showed a slight increase the number of sunspots. The increase did not match the drop from the month before, but it brought the activity back up to the level seen during the summer.
The graph above has been modified to show the predictions of the solar science community for the previous solar maximum. The green curves show the community’s two original predictions from April 2007 for the previous maximum, with half the scientists predicting a very strong maximum and half predicting a weak one. The blue curve is their revised May 2009 prediction. The red curve is the new prediction, first posted by NOAA in April 2020.
The Sun continues to confound the experts. Only two weeks ago the experts at NOAA announced that we are now in solar maximum, though the actual peak won’t be known until activity starts to decline.
The activity in October suggests that if this new prediction is correct, the maximum will be a weak one, though far stronger than predicted by NOAA’s panel (as shown by the red curve). It would be a mistake however to accept this conclusion. The maximum was originally not supposed to occur until early 2025. Instead, it arrived much earlier than expected. And there is still plenty of time for sunspot activity to go up or down significantly from the present level before the Sun calms down and begins the ramp down to solar minimum.
Based on the activity so far this maximum, it is completely impossible to predict what will happen. We could see activity jump up far beyond the high level seen two months ago, or decline to match the prediction curve. Or it could continue to fluctuate between the two.
There is one prediction I can make with utter confidence: The Sun will surprise us, and do things no one predicts.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
